qwerty it is less frequently used as a password and less likely to pop up in other textual references for example the QWERTY keyboard is not named the ASDFGH keyboard. The zxcvbn is the other brother to asdfgh and is the youngest. Asdfgh has been seen less of because the

Asdfgh is equally important to the world renowned
qwerty and the less heard of zxcvbn.
